Duilio Capponi

Duilio Capponi (died 1923) was a Masseria crime family enforcer under Gyp Rosetti's crew. In 1923, Capponi was sent to guard the Artemis Club in Atlantic City, New Jersey, where he forced Richard Harrow to leave the building on Gillian Darmody's request. Harrow would later return with an arsenal of weapons and kill Capponi and the other Masseria guards.
